Re: Fedora 16 boots slow because of extra swap line in /etc/fstab
Any invalid UUID number in fstab can result in a slow boot. I had recreated my SWAP partition on an third Linux OS install which changed the UUID number for it in Fedora. Like you, I noticed Fedora booting noticeably slower than before.
You can run blkid to find the current UUID numbers for your partitions, and edit fstab accordingly.
